WATER-BACK FOR RANGES.

l Specification forming part of Letters Patent No. 19,368, dated February 16, 1858; Reissued J' une 21,

To all whom t may concern:

Be it known that I, JAMES INGRAM, of the city, county, and State of New York, have invented, made, and used certain new `and useful Improvements in Movable Water- Backs for'Oooking-Ranges; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawing, making part of this specification, wherein- Figure l, is a plan of a cooking range with the top plate removed to show my improved water back, and Fig. 2, is a. vertical section of the range near the center of the same.

Similar marks of reference indicate the same parts.

Many of the cooking ranges, both in the city and country, where a competent supply of water exists, are fitted with water backs to heat, by circulation, the water contained in a boiler standing near the said range. The water back, to be sufficiently operative, is in contact with the fire, and will heat suflicient hot water for washing and other domestic purposes. Then the range is being used for ironing, particularly, but little hot water is required, and an intense ire is in contact with the water back; hence it is found practically that steam is often formed in t-he water back, that drives the water out of the adjoining boiler causing an overflow of the cistern (if one be used) and often collapsing the boiler and splitting the water back when the cold water rushes into the boiler, condensing the steam, and running into the highly heated water back, injuring or splitting the same. Besides the foregoing diiiiculty with water backs, another often arises in the country places when a continued drought exhausts the reservoirs or wells, and there is not suilicient for supplying the hot water boiler, in this case the range cannot be used for fear of burning out the empty water back.

The nature of my said invention consists in setting the water back in such a manner that it can be slid away from t-he fire and a soap stone or fire brick or equivalent nonconducting substance, introduced between the fire and the water back, thus obviating all the inconveniences and dangers before enumerated.

In the drawing a, is the ire place of any desired character of range, o, o, the ovens.

The iiues and other parts are to be of any character, and not relating to the water back need no further description.

c, is the water back shown in its usual place 1n Fig. l, with the circulating pipes (Z, e, to the boiler f.

g is the brickwork or setting of the range.

In almost all cases the distance between the boiler y" and water back c, is such that the pipes d, e, will spring two or three inches without disturbing the joints if the parts are otherwise unobstructed; I therefore lit my water back c, to slide on supports l, 1, back and forth, and approach to or recede from the fire; and to move said water back with facility I provide levers 71, it, on fulcrums 2, 2, joined together by a rod 3, and connect said levers with the water back by links 4L, 4. The space in which the water back moves is made tight by the bottom plate 5, and top plate 6, which is provided withV a cover 7,A to allow access tothe levers h, to move the water back, the object being to prevent heat being drawn under said water back by any draft.

Then the .water back has been drawn away from the iire a soapstone or re brick (z,) is to be inserted between the fire and said back and this may be placed in by hand and rest on a suitable ledge or support, or the said stone or fire brick may be on one end of a lever 7o, on a fulcrum 8, and move up and down in the space Z, (Fig. 2,) and be balanced by the weight 9, sothat when the water back is moved to the rear the lever and weight shall force up the intervening stone or brick, and when desired to increase the amount of heated water, the lever 7c, is to be acted on by the small rod 10, to depress the brick or stone while the levers 71, 7L, are used to move the water back up to the fire again.

h/Iy water back can thus be in contact with the fire when required, or almost instantaneously protected from the -same in the manner and for the purposes before enumerated. And besides the foregoing diticulties it will be proper to ment-ion the fact, that in case any of the plumbing work in the house requires repairs so that the water h as to be let oif, the fire in the range has to be extinguished and so remain until the repairs are completed, while with my movable water back the range can be in use all the time whether there is water in the back connections substantially as and for the purposes speciiied.

2. And in Combination with said movable water back I claim the lever c and weight 9 to move the intervening soap stone or ire brick, substantially as specified.

In witness whereof I have here-unto set my signature this iifth day of January 1858.

JAMES INGRAM.
